Oscar-nominated musician John Legend (for the song “Glory” from the movie “Selma”) joined Vanessa Kirsch, CEO of the Boston-based venture philanthropy firm New Profit, at Fashion Week on Tuesday night to announce the launch of “Reimagine Learning,” a program that will support personalized education for kids. New Profit, which has already raised $30 million for the cause, is working with WME-IMG on the project. The MIT Media Lab has already been chosen as one of the recipients. Kirsh told us that the partnership with WME started after she bonded with WME boss Ari Emanuel about their experiences growing up with dyslexia. She said that Legend came aboard because it falls in line with his work with the LRNG Innovation Challenge, which gets grants to teachers. Kirsch told us that Legend — who used to live in Boston — has made it clear that he’s more than just a celebrity spokesperson. “He really walks his talk.” The night included a performance by Legend and a fashion show.
